Abstract

The α-Keggin ions [TNb₁₂O₄₀]^16- (T = Si, Ge) have been synthesized hydrothermally as water-soluble sodium salts. These clusters are very highly charged, and are bound to their charge-balancing sodium atoms in the solid state (see picture). NMR spectroscopy experiments show that the sodium atoms remain strongly associated with the clusters in solution.
